Site A, abundant in multi-year ice floes, presented the severest ice conditions of the entire voyage (see the description of the Ion Ice Massif, Section 3.2.3). In the other sites, the ship speeds were 4-5 knots at Site B , 6-8 knots at Site C and 8-10 knots at Site D (see the description of the Taymyr Ice Massif and North Kara Sea Ice Massif, Section 3.2.3). As Figure 5.5 shows, ship speed is dependent on the ice concentration, so that speed decreased as ice concentration increased. It should be noted that the Kandalaksha experienced no continuous vast or giant floes but only small and medium floes throughout the voyage.
